When you say slow response, when you change direction does the lighting immediately change and such but just takes a while to move while dialing the throttle?
These are Pullmor motors and you might have to set the Stall setting as it takes a lot to get these to move. The stall setting allows the initial voltage to the motor to be greater to get to the point quicker where the motor can operate. Not sure if thats what you mean by slow response.
